It was evaluated intake, total apparent digestibility, performance and feeding behavior of bovine fed diets constituted of corn silage, crushed sugar cane given fresh or crushed and given 72 hours after storage, ensilaged sugar cane with or without 1% of calcium oxide and concentrate at the proportion of 1% of the body weight. It was used 35 bovines, distributed in a random block design, with 5 treatments and 6 repetitions. The animals were housed in collective stalls with troughs individualized […]

The objective of this study was to evaluate the effects of inclusion of by-product of fresh fruit (pineapple, guava, papaya, mango and passion fruit) used in the diet for bovines partly replacing corn silage on intake and total nutrient digestibility, on the production of microbial protein and the nitrogen balance and on prediction of digestible fractions and total digestible nutrients (TDN) of these by-products. All animals received corn silage and the urea/ammonium sulfate (9:1) mixture so diets would remain isonitrogenous. […]

It was evaluated intake, rumen and intestinal digestibility and passage and digestion rates in bovines fed diets constituted of corn silage, crushed sugar cane and given fresh, crushed sugar cane and given after 72 hours of storage, ensiled sugar cane with 1% of calcium oxide and with no treatment and a same concentrate fixed at 1% of body weight. All roughage was corrected to contain 10% of crude protein. It was used five rumen-fistulated bovine with average weight of 240 […]

The objective of this work was to evaluate the effect of the levels of lactic and propionic acids on in vitro fermentation of ruminal microorganisms. In experiment 1, the levels, in a total of 12 were the following: addition of 0 (control 1), 50, 100, 150, 200 and 250 mM of lactic acid and 0 (control 2), 50, 100, 150, 200 and 250 mM of propionic acid, respectively, in incubation flasks, which contained ruminal inoculum, glucose and synthetic culture medium, […]

It was evaluated grazing times of heifers in natural pasture, obtained by visual assessment in 5-minute intervals. By using the original data, it was calculated observation intervals of 10, 15 and 20 minutes. It was used four crossbreed Angus × Nellore heifers, with average weight of 249 ± 6 kg BW. The completely randomized block design was used with four treatments (forage allowance of 4, 8, 12 and 16 kg DM/100 kg BW) and two replicates, and type of soil […]

The effects of skin temperature (TS) on the rate of heat loss by cutaneous evaporation (ES) in Holstein cows chronically exposed to sun, considering hair coat colour were studied. Sixteen purebred cows were measured for ES and TS at 01:00 p.m. after 6 hours of exposure to sun, on three body regions (flank, neck and gluteus) and considering dark and white spots separately. Sweating rate (S) and ES were measured by means of a ventilated capsule. Black skin areas presented […]

The objective of this work was to evaluate nutritional characteristics of meat from lambs finished on feedlot with diets containing sugar cane or corn silage on two roughage:concentrate ratios (60:40 or 40:60). It was used 32 non castrated Ile de France lambs, with 15 kg of body weight distributed in a complete random experimental design in a 2 × 2 factorial arrangement. The animals were confined in individual stalls and slaughtered at 32 kg. Lamb meats had 74.55% of moisture, […]

The objective of this work was to characterize the intramuscular fat of short loin, ramp loin and rib and six commercial brands (A, B, C, D, E and F) of beef commercialized in Porto Alegre, Rio Grande do Sul. Samples were collected from a supermarket chain. The brands A and B were associated with British animals breeds, the brands C and D were from European animals breeds produced in conventional and organic system, respectively, from Uruguay, while the brands E […]

The objective of this study was to evaluate the different contents of neutral detergent fiber from forage at advanced maturity on intake, digestibility of the dry matter and of nutrients, nitrogen balance, milk production, efficiency metabolizable energy use and the ingestive behavior of lactating goats. Five dairy goats were distributed in 5 × 5 Latin square by using increasing contents of neutral detergent fiber from forage as independent variable. Concentrations of neutral detergent fiber from forage used were 20, 28, […]

Two experiments were carried out to evaluate the effects of particles sizes on contents of neutral detergent fiber (NDF) by using nylon bags F57 (Ankom®) and non-woven textile (NWT 100 g/m2). In the first experiment, to check contents of NDF obtained with each one of the textilles, quantitative filter paper (purified cellulose) was used as analytical standard. The material was processed in a 1 or 2 mm and put in the bags in a ratio of 20 mg of dry […]
